This commit makes the coefficient tree initialized prior to token
initialization, where the coefficient costs are filled out according
to the probabilities associated with coefficient value categories.

This commit fixes the intra prediction reference source selection
in the settings of skip_encode. Use original boundary pixels as
prediction reference, when the inverse transform and reconstruction
are skipped in the per block size rate-distortion optimization loop.

This commit fixes the use of uv_intra_estimate by properly restoring
the mode_info struct required by rd_pick_intra_sbuv_mode.

The idea here is to allow "in frame" adjustment of the final Q
value used to encode each SB64, using segmentation.
There is also adjustment of the rd mult in regions of overspend.

When calling check_initial_width through vp9_set_size_literal
the function was defaulting to using non-subsampled chroma.
This patch changes the default to assume sampled chroma as
an interim solution until complete support for other
color formats is added.

This commit takes out vp9_extend_frame_borders from
vp9_setup_scale_factors.
The refactoring is for the preparation of the use of lazy border
extension at decoder. This makes it necessary to handle border
extension separately at encoder/decoder. The use of
vp9_extend_frame_borders will be removed, when lazy border extension
is ready.

Moves all rate control variables to a separate structure,
removes some currently unused variables,
moves some rate control functions to vp9_ratectrl.c,
and splits the encode_frame_to_data_rate function.

Simplifies the code by implementing band mapping with static arrays.
A lot of the code complexity introduced in a previous patch
disappears.

The switch to the rate-correction damping factor
in https://gerrit.chromium.org/gerrit/#/c/67536/ was not conditioned on CBR mode.

Overall change (using dual buffer scheme for superblocks of both inter
and intra modes) reduces speed 2 runtime:
bluesky_1080p at 6000kbps: 263553ms -> 257441ms
riverbed_1080p at 8000kbps: 233230ms -> 225308ms.

Implements scan order to band map with arrays in both the encoder
and decoder to remove conditional statements.
Encoding seems to be about 1% faster at speed 0, tested on football.
Decoding seems to be about 0.5-1% faster on a set of 25 videos.

This commit enables the dual buffer rate-distortion optimization
and encoding scheme. It stacks the original transform coefficients,
quantized levels, and reconstructed coefficients, in the rate-
distortion optimization search process, hence eliminates the need
to re-run residual generation, forward transform, and quantization
in the encoding stage.

Allocate memory space of dual buffer sets that store the coeff, qcoeff,
dqcoeff, and eobs. Connect the pointers of macroblock_plane and
macroblockd_plane to the actual buffer in use accordingly.
Change-Id: I2f0b5f482ca879fae39095013eaf8901db20a5a4
Make the macroblockd_plane contain dynamic buffer pointers instead
static pointers to the memory space allocated therein. The decoder
uses the buffer allocated in pbi, while encoder will use a dual
buffer approach for rate-distortion optimization search.

SVC multiple layer per frame encoding is invoked with vpx_svc_init and
vpx_svc_encode. These interfaces are designed to be invoked from ffmpeg.
Additional improvements:
- make dummy frame handling a bit more explicit
- fixed bug with single layer encodes
- track individual frame sizes and psnrs instead of averages
- parameterized quantizer, 16th scalefactors, more logging,
- enabled single layer encodes to generate baseline
- include new mode for 3 layer I frame with 5 total layers

Removed:
goldfreq, avg_encode_time, avg_pick_mode_time,
cpu_freq, interquantizer
member variables from VP9_COMP since they are no longer
used in the code.

Removed three members from the VP9_COMP data structure:
inter_zz_count, gf_bad_count, gf_update_recommended.
These were part of the VP8 real-time mode implementation
that was removed from the initial VP9 codecbase.

-Don't reduce maxQ for gold/alt in CBR mode.
-Fix to min/maxQ for first/initial key frame.
-Add more speeds to datarate test and reduce the starting bitrate for test.

For consistency with idct function names. Renames:

The pointer was asigned only once with vp9_regular_quantize_b_4x4, calling
this function directly now. Also removing unused declarations:
prototype_quantize_block
prototype_quantize_block_pair
prototype_quantize_mb
vp9_regular_quantize_b_4x4_pair
vp9_regular_quantize_b_8x8
